Problems solved by technology

[0003] Existing jetting photosensitive polymer 3D printers usually move down a certain distance after the jetting and printing of one layer are completed. Since the height of the photosensitive polymer jetted each time is not exactly the same, the printer will be damaged after being used for a period of time. , the distance that the worktable moves down may not match the height of the photosensitive polymer, thus affecting the printing effect

Abstract

The invention relates to a printing method for a photosensitive polymer jetting 3D printer, wherein an image acquisition device acquires an image U1 of laser on a worktable before a polymer is jetted; the image acquisition device acquires an image U2 of laser on the worktable after the polymer is jetted and solidified; the height H of the polymer is determined at the time according to the images U1 and U2, the displacement distance of the worktable is determined according to the height of the polymer, then the downward displacement distance of the worktable accords with the height of the polymer, the image is acquired after the photosensitive polymer is solidified, so that the height variation caused by the solidification process of the photosensitive polymer is effectively prevented, and therefore, the calculation of the height is more accurate.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a printing method for a photosensitive polymer 3D printer. Background technique [0002] At present, a 3D printer, also known as a three-dimensional printer, is a printing device that uses rapid prototyping technology, based on digital model files, and uses molding materials to construct a three-dimensional entity through layer-by-layer printing. With the rapid development of 3D printing technology, 3D printers have been widely used in product manufacturing. 3D printing technology is known as the "third industrial revolution" and is widely used in industries, medical care, teaching, aerospace and other fields. The basic principle of 3D printing is layered processing and superposition forming, that is, to generate 3D entities by adding materials layer by layer. The information is sent to the 3D printer, and the 3D printer stacks successive thin layers until a solid object is...
